Where did you get your info? The car engineered in Australia and there have been no tests that I've seen so far.

I can tell you the G8 was almost as good as any BMW Ive driven and the Camaro SS 1LE and Cadillac ATS sound amazing in their reviews. I love BMWs but Im not full of kool-aid either.

Same here, I had a 2009 g8 gt. Felt just as good as my 335i. Only difference with the interior is nicer in the bmw. i bailed on the pontiac though because they went out of business. i didn't want to deal with stupid service trying to get parts. When i saw the SS announced, I'm about 90% sure I will be trading in my 335i for one.
I just need to hear more detail first.
